That's a weird way to put that. American newsletters have an unsubscribe link because our Congress passed a law in 2003. But Americans lets prescription drugs advertise on television, which is an indefensible barbarism. So it goes. Every country has a different vision of what nuisances are and are not worth of regulation.
>Urban Landscape – Walk around one of Tokyo’s main hubs like Shibuya and you’re constantly bombarded with bright neon advertisements, noisy pachinko parlours (game arcades), and crowds of rambunctious salary men or school kids
The only American analogues to such a design would be some parts of New York City and Las Vegas. Not even Los Angeles, San Francisco, or Chicago as mega metropolitan areas have this kind of "density". Japan has a third of the population crammed into less than 5% of the land area. So adverts have a lot more incentive to just cram everything into a city block compared to any american city
But there are many huge Japanese internet based companies, like Zozotown, that are extremely savvy at their UX experience and are extremely metrics driven. Not to mention the recent surge of internet based cellular providers that don’t have a brick and mortar storefront.
Meanwhile the fax machine anecdote is about ten years old at this point. Most Japanese purely rely on mobile devices these days.
My wife's small business included a fax, but it didn't get much use after around 2014-2015 or so, I think. The next couple of years you could occasionally hear a call to the fax machine but it was always just some random ad spam. We let it all go to /dev/null. Nowadays her work space is rented out to a small service firm and they don't use a fax at all as far as I know. Internet and phone services were super important to get set up though.
Even in the TV shows in Japan, it's a whole trashy mess of colours and patterns and huge subtitles flying around the screen.
